Using Serial Search and Navigation
Searching through a deep memory acquisition of serially decoded data can
sometimes be a tedious process. But with InfiniiVision’s new Search and
Navigate capability on the 7000B Series DSOs and MSOs, finding specific
serial events is much easier now. In this lab we will first use a manual
process for reviewing captured serial packets utilizing the serial decode
“lister” display. We will then use the new automatic Search and Navigate
capability that is available on this oscilloscope. Although the instructions for
this lab are based on using the CAN serial bus demo signal, if your
oscilloscope is not equipped with the CAN/LIN option, you can use one of
the other serial bus signals and options that your oscilloscope may be
equipped with. However, we suggest that you first become familiar with that
particular serial bus by referencing one of the previous serial bus labs. You
can verify the installed options on your oscilloscope at [Utility] > Service >

Setup
1 Connect the demo kit’s 40-pin ribbon cable from the back of the Agilent
InfiniiVision Series oscilloscope to the 40-pin connector on the demo
board.
2 Connect channel 1 probe to the CH1 test point and ground (GND).
3 Connect channel 2 probe to the CH2 test point and ground (GND).
4 Set the rotary switch on the demo board for the “CAN” signal (Mode #8).
5 Press [Default Setup].
6 Set the channel 1 vertical scale to
500 mV/div and the vertical offset to
1.0 V.
7 Push the Trigger Level knob to set the
trigger level at 50%.
8 Press [Serial]; then, select the CAN
decode mode.
9 Press Settings.
10 Press Baud; then, select 125 kb/s.
